I just started work and my LO wakes up more to drink at night. It is so tiring. Any suggestions to help me?

I think u need to make sure lo is really full before u put lo to bed, u might wan to increase the amount that u feed lo before sleep to try ~not sure if u believe, but I notice when my lo sleep in air con he will sleep throughout the night but if he sleep with fan he will wake up once in the middle of the night~
